[Theory] Who was Izunia?

[Chrysalis]

I have a theory about Ardyn, that some of you might find interesting. It's about the possible origin of the name Izunia and why Ardyn took it as his own.

There are already a lot of great theories on the internet about this topic and many of them could be true. Especially, this popular theory, that states, that Izunia was the name of Ardyn and Somnus before they were chosen by the crystal and given the name "Lucis Caelum". This theory seem plausible to me, but I have another idea why he is named Izunia.

My theory is a little different and it's based on a scene from the Ardyn DLC.
This scene plays in a base in Niflheim after Ardyn has a nightmare about Aeras death and is awakened by an announcement over the intercom that requests him to go and speak with Verstael Besithia.
In this announcement, he is already called "Ardyn Izunia", but this scene plays before he turns Ifrit into a demon and becomes evil himself.
At that time he is still himself and hasn't absorbed the memories of many people. In the timeframe of the main game, it is said that he can barely recognize his own existence anymore, becaus of all the people he turned into demons, but this isn't the case yet, he is still himself in this scene.
At that moment he had only absorbed the memories of a single person, one of the Kingsglaives that attacked the imperial soldiers trying to remove Ardyn from his imprisonment on Angelgard/Mikage Island.

So maybe this single Kingsglaive, the first to be turned into a demon and having their memories absorbed by Ardyn, was named Izunia. Ardyn couldn't use his birthname "Lucis Caelum" anymore, because he needed to hide his true identity, so he took on the first name he heard after his imprisonment, Izunia.

I hope you liked this little theory of mine!

What do you think about it? Do you agree with me or is my theory completely false in your opinon? Did I miss something?

I'm open for any suggestion and opinion, so please let me know what you think about this theory!

The episode Ardyn prequel anime implies Izunia was the name of the Lucis Caelum family before they became royalty.

Hm, I watched the anime about two months ago, but I can't remeber them mentioning or alluding to the name Izunia . Could you please tell me how they implied this?
